L'Wren's sister Jan Shane says the Rolling Stones legend is "grotesquely disrespectful" and says "his life goes on as if nothing happened"

Tragic L’Wren Scott’s sister has launched a savage attack on Mick Jagger after it emerged he met his balcony lover weeks before the fashion designer’s suicide.

Speaking after the Sunday Mirror’s exclusive story revealing the identity of Jagger’s latest lover, Jan Shane said: “The more I think about it, the angrier it makes me. My sister deserves more respect.

“It hasn’t even been three months since she died. I now believe that he was a bigger part of her troubles than we knew about.

Jan, 53, of Utah, US also labelled her late sister’s boyfriend “grotesquely disrespectful” after learning he flew ballerina Melanie Hamrick, 27, from the US to stay with him in Zurich, where on June 1 they were seen embracing on his hotel balcony.

She added: “It doesn’t surprise me at all. I’m just really glad that L’Wren doesn’t have to put up with him any more.

“My sister deserved so much more than that. It’s a terrible thing for Mick to have done. It’s sad. His life goes on as if nothing happened. He’s still out with women, but a huge part of our family is missing.

“She had accomplished so much without him. She was amazing in so many people’s eyes. He just needs to quit dragging her name through his cr*p!”

The Sunday Mirror revealed the Rolling Stones legend , 70, met Melanie backstage at a Rolling Stones concert in Tokyo 11 days before L’Wren, 49, hanged herself in her New York apartment on March 17.

Sources say the Rolling Stone made a “beeline” for the beautiful dancer.

Angry: L'Wren Scott's sister Jan Shane

Less than three months later she flew in to Switzerland to stay at the five-star hotel where he was staying with the Stones on tour. Insiders in Jagger’s camp say the “friendship was not consummated” until this meeting.

The US ballerina, once engaged to a dancer 20 years her senior, lives a five-minute drive from L’Wren’s home in Manhattan, New York. Yesterday she refused to talk after answering her phone.

Dad of seven Jagger yesterday spent Father’s Day in Vienna, Austria, with family and his ex Jerry Hall before a Stones gig.

Sources close to the singer say Jerry hopes for a reunion but he is happy being single, having “enjoyed” several liaisons.
